Hi Jeremy,
This is probably far too late but here goes:
1) Re vector types. I believe that Kyle Wilcox is working on integrating the
latest ncWMS with THREDDS, and hopefully including his work on different kinds
of vector plots, including barbs.
2) ncWMS/THREDDS can't return a timeseries as JSON at the moment, but can do so
in a simple ad-hoc XML format. Just set the INFO_FORMAT to text/xml instead of
image/png. (It probably wouldn't be too hard to add JSON support too.)
Hope this isn't too late to be helpful!
Jon

Subject: [thredds] ncWMS and vector plots, point time-series as JSON

I'm working to provide browser/openlayers/javascript type GIS map images of
wind or current vector fields as barbs or arrows(speed+direction) from provided
model or in-situ U/V components and when clicking on a map point providing
time-series for the data at that point. Currently I'm having to go through
some intermediate steps of converting data to shapefiles(which take up storage
space) for mapserver based vector styling and/or generated image files at a
fixed zoom level(less space used, but still some supporting setup and
processes).
Saw this earlier thread about possible thredds support for these vector type
plots(from u/v components), but haven't seen other mention or examples since
and just checking to see if any updates.

When doing a getFeatureInfo with ncWMS it's possible to get a single time point
- if ncWMS/thredds could support URL references for a time-series at a point
returned as JSON, that would also be very handy substitute for existing work
I'm doing writing my own custom wrapper scripts(pyDAP to JSON).
Thanks
